Application filed March 28, 1919. Serial No. 285,836.

Be it known that I, FERNAND PAUL Man- TiN7 engineer, citizenof the French Republic, residing at Paris, France, have invented `.certain new and useful Improvements in .iXpparatus for Delivering lVlaterials7 of which the following is a specilication.

Thein'vention relates to apparatus which are designed to deliver materials in fractions ofequal Weights, such as meters, and has 'for its object to build apparatus of this kind in a simpler and more accurate mani ner than hitherto.

Theinvention comprises a drum divided by partitions into compartments occupying equal sectors of the said drum, the said drum being suspended to an oscillating system arranged so that it allows the drum to `bellocked in its position of rest when it is empty, and that it balances the latter when a given quantity of material has been introduced into one of its compartments, Whereby .if an additional quantity of material introduced into the said compartment, i

the said drum moves, discharges its contents and acts through a suitable device on .the oscillatingfvsystem so as to return the said drum to its position of rest.

The invention further comprises other arrangements, more explicitly referred tol hereinafter and claimed in the claims.

The single ligure of the said drawing 'shows diagrammatically in verticalv section an apparatus according to the invention.

The invention will be described as applied to a Water meter having a drum a .constituted b v'tivo opposite faces connected 'together by radial `metal sheets al forming a number 'of compartments kor buckets o preferably kof the same dimensions and arranged insectors uniformly about the horizontal spindle a2 of the drum.

The drum ci is provided on its circumference with a number of. projections or teeth i3 equal to the number of buckets arranged at regularintervals, and also with the same number of tenons 1.4 arranged at regular distances and all radially equidis-r tantfrom the spindle ci?. At a fixed point is arranged a part c which forms a stop for any7 ofthe teeth (L3, When the drum a rotates -smaller inthe direction of the ai'roiv. The position of the drum when stopped is that in which a vertical plane passing through the spindle o2, intersects one of tlie'buckets which is above the said spindle, so as to divide the said bucket into tivo portions of slightly different volume, the greater poi'- tion being at the side of the direction of .rotation indicated by the arr'oiv.

The spindle a? of the drum is rotatably supported between the tivo ends of a lever (Z. The said lever is pivoted to a fixed horizontal spindle c at'one of its ends, and so that .when the lever (Z makes a "suitable `oscilla'- tion about the point @and the'd'rum a makes an also suitable rotation about its spindleI (t2, any one ofthe teeth a3 can strikethe part c and prevent the drum from rotating.-

Any means for balancing'the movablesystem may be used, assuming that one bucket contains a vgiven quantity of Water, so that the least additional quantity of Water introduced into the said bucket, tips the system. A suitable Weight is arranged to act on the lever d, so that the latter raises the drum and presses one of its teeth a against the stop c. `To this end a. lever f is provided between its ends'with a knife edge f1 which is supported on a` fixed support g thereby being fulcrumed at that point. One of the ends of the said lever is provided with a balance Weight f2 (which is preferably arranged so that it can be moved on the lever), andthe other end of the lever f, is connected to the end of the lever CZ, which is opposite to the pivot c, bynieans of a v' part which is supported bya knife edge 71.1 on the lever f, and is also pivoted at (Zi tothe lever (Z. x f

`The apparatus being in they position 'of rest, that is, ywith one of its teeth t3 engaging vwith the part c and theupper bucket being in the position already mentioned, if ivater is introduced into the said bucket, for instance through a nozzle i-ivhich in the neighborhood of the upper part ofthe partition corresponding to the portion vof volume of the said buckettlie system will :first be in equilibrium, and then the said equilibrium will be disturbed. The

drum then descends 'owing to its`weight,1

disengaging the tooth a3 and turning about the joint c of the lever d, and at the same time begins to rotate in discharging its contents, While the next bucket begins to receive Water. Then the balance Weight raises the lever (l, after the contents of the first bucket are discharged through the medium of lever and connection L, carrying with it the ydrum which returns to its position of rest, the next tooth a3 sriking the part 0. The second bucket is then held in Vposition until the Weight of the Water introduced into it produces a fresh movement insuring its discharge. The apparatus is adjusted, so that the return to raised position is initiated and assisted by one of the tenons a4 acting on one of the arms jl of a bell-crank lever pivoted about a spindle 7c' parallel to the spindle a2, so that the other arm 7'2 raises at the desired moment the joint Z1 of the lever (Z, which acts on the part 7L through the intermediary ot a projection h2 provided on the said part, thus holding the drum in locked position until a suiiicient amount of material has been discharged from the drum to permit Weight f2 to retain the drum in its elevated and locked position. The said tenon ceases to engage With the arm jl at a moment suitably determined, in order that the drum returns in the desired time to its position of rest, at the same time as the lever y'.

By the movement ot rotation ol' the drum a a. counter or meter of any desired type can be operated to indicate the number of discharges of buckets, and therefore, knowing the volume of Water that a bucketl holds, the total volume and Weight of the Water delivered during the course of the operation will be known.

rIhe meter, as Well as, if desired, a recording instrument with diagrams, can be operated direct in any desired manner by means for instance of a guided rod driven by one on the movable parts of the apparatus; and, for instance, by the arm i2 of the lever j, the said rod being provided with a tappet Which acts, at each discharge of a bucket, on the driving linger on the meter yand on apivoted pen intended to draw diagrams on the drum ot' the'recorder.

The meter and the recorder may also be operated indirectly and from a distance, in also any suitable manner, for instance by means of a suitable fluid, a pneumatic system, or an electric system.

Obviously the parts of the apparatus described and shown in the diagram can be mounted on a single frame and the apparatus can be advantageously inclosed in a closed casing provided with a Water inlet and outlet.

The apparatus described can be utilized not only as a fluid meter but also for automatically Weighing solid materials in poivder, grains or fragments. The distributer for the introduction of the said materials into the apparatus is arranged to suit the nature oi' material to be treated and to obtain a good distribution in the buckets. The said distributer is of course arranged so that it Works only under the action of the Weight of the material.

This apparatus moreover can have numerous applications. It can be used for mixing various materials. Its movements can be utilized either for direct control, or for control by a servo-motory or for tele-control of valves or devices for closing and opening pipes of the distributer or any other pipes, as ivell as `for starting, stopping, or regulating motors, pumps or other devices.

Obviously the invention is not limited to the construction described, but comprises any modiiications Within the scope of the claims.

Having now particularly described and ascertained the nature ot my said invention and in what manner the same is to be performed, I declare that what I claim is:-

l. vIn an apparatus for delivering material in measured quantities, ay lever adapted to oscillate about a fixed pivot, a measuring drum pivoted to said lever and comprising a. plurality of compartments for the material to be measured, means 'for supplying the material to said compartments, lugs formed on the periphery oi said drum, a fixed paivl adapted to engage said lugs, a lever pivoted above said drum having a Weight slidably mounted thereon, a link connecting said levers, said drum being adapted to move out of Contact with said pawl as the material in one of said compartments overbalances said Weight, and means for initiating the return oil said lever and drum to rest position after the contents of one of said compartments has been discharged.

2. An apparatus for delivering materials in measured quantities comprising a lever adapted to oscillate about a. fixed pivot, a measuring drum pivotally secured to said lever, said drum having a plurality of compartments for the material to be measured, lugs formed on the periphery of said drum, projecting tenons from the side faces of said drum, a leverpivoted above said drum and having mounted thereon a Weight, a link connecting said levers, and a crank arm positioned on a fixed pivot adjacent said drum and adapted to be oscillated by said tenons as the drum is rotated.

3. In an apparatus for delivering materials in measured quantities, a lever adapted to oscillate about a fixed pivot, a measuring drum pi'votally mounted on said lever, means for normally locking said drum against ro` tation, said drum being moved out of engagement with said means by the downward movement of said lever whereby said drum is released and may rotate when a certain quantity of material has been placed therein, a Weighted lever tending to return said rst named lever to normal position, and means for initiating ythe return movement of said first named lever.

In testimony whereof I have hereunto Set FERNAND PAUL MARTIN.
